Bombs don't really have a standard attack and that means they have to charge before attacking. Often other knights using swords and guns rush in first and suddenly have all of the monster aggro. The problem is that bombers work best when they have all of the aggro.
So what I propose is "flashing" your bomb. Your knight would hold the bomb with one hand above their head monsters would be naturally aggroed to it. Also when holding using the flash there would be a very small AOE around your knight that does damage. All the bombs would have a 3 "swing" standard attack. This would do minimal damage and have low flinch change, no status either.
Hold up bomb, flash light and damage, and after the combo your knight winds up the bomb to be used again.
Note: This flash will affect all enemies within standard blaster gun range
Like the idea, and it could potentially mean that slower charging bombs have smaller "combos" and whatnot.
Why not have the bomb do a big *smack* to enemies in the area? Basically a much smaller AoE affect that deals minor damage.
Either that or standard attacks drop bombs with a very small radius at our feet that explode shortly after. Basically a mini bomb of the one we're using. (mist bomb at 5* would drop a 1-1.5 tile radius mist bomb that would last for a second or two) When we get hurt we could even have a chance to drop one of these (with a 200% chance at dropping a heavy deconstructor) like a darkfang demo.
Having bomber armor naturally aggro enemies would be a nice change to the armor however. Makes chaos bombing less rewarding/more frustrating.
